Three devices for ventilating mines with bellows. In the centre the horse turns the wheel and cams, I,I, work the bellows. At the top, a horse turns a crown wheel which engages with a lantern on the camshaft and the cams engage with tappets to work the bellows. At the bottom, a man works the bellows by foot.
